My bike was service on 22/07/2018. After service i found that my bike handle is jam. I was reach service center on 26/07/2018. But supervisor mishra asked me that please book your bike for normal service. Is it reqd? Or remove the peoblemp from the bike. I am complaining that this service centre is working well. When send your bike for service they pose nitrogen air on wheel.
